NEWLY ENGAGED!!!!!

My name is Simone and I am newly engaged!!!!! I am so excited to plan a wedding for me and my soul mate. I have a couple of destinations in mind (i.e. Jamaica, Cayman Islands, Bahamas, St. Lucia), but I am having a hard time selecting an all inclusive resort that is affordable to my guests (expecting 70-80 people) and child friendly. Does anyone have any suggestions? Thanks in advance.
